Triangulation invariance of statistics for topological excitations

Let pp be the excitation dimension, let GG be a fusion group, and let MM be a triangulable topological space. For any triangulation CC of MM, write Tp(M,G)T_p(M,G) for the statistics of pp-dimensional topological excitations on MM and Tp(C,G)T_p(C,G) for the corresponding statistics on CC.

Triangulation-invariance conjecture. There is a good definition of Tp(M,G)T_p(M,G), and

Tp(M,G)Tp(C,G).T_p(M,G) \simeq T_p(C,G).

This would make the statistics independent of the chosen triangulation and extend the simplicial construction to triangulable topological spaces. The source explicitly leaves both the definition and the claimed invariance conjectural.
